Yes, I indirectly touched on this in an earlier message:
DB>  Here's one way: 
DB>          zUr2=: (2$:1 0,~1+]) : ([EMAIL 
PROTECTED](>:@[$:],1,0$~1={)@.(<:{.)) 
DB>          zUr4=: }.@:zUr2 f. 
DB>          zUr4 
DB>       }.@:(3 : '(2 $: 1 0 ,~ 1 + ]) :([EMAIL PROTECTED](>:@[ $: ] , 1 , 0 
$~ 1 =
{)@.(<: {.)) y' :(4 : 'x (2 $: 1 0 ,~ 1 + ]) :([EMAIL PROTECTED](>:@[ $: ] , 1 
, 0 $~ 1
= {)@.(<: {.)) y'))

BTW Raul, I didn't miss your last post in the "gerunds from explicit verb
results?" thread.  But while composing a response, I was led me onto an
interesting tangent.  I may have something interesting this weekend.
